Put the bananas, eggs, vanilla essence oil and milk in a blender. Pulse for a few seconds, until you get a smooth, creamy paste. Add the flour and baking powder, then then whiz for a few more seconds. Add more milk, if needed – you should have a thick, but pourable batter.
Heat the waffle maker. Once it’s hot, spoon in the batter, then seal. Following the machine instructions, cook the waffles for about 5 minutes - they should be golden brown and crispy. You should be able to get 3 or 4 waffles from the mixture (depending on the size of your machine).
Meanwhile, make the strawberry compote.
Cut the strawberries in half and put them in a small pan. Add the lemon juice, vanilla and a drop of water. You can add a little sugar, if the strawberries are not sweet and ripe. Cook for about 5 minutes, until the strawberries are tender and you have a thick syrup around them.
Serve the waffles with the strawberries and the syrup.
